Vitamin D – A Vital Nutritional Tool of the Body

What Do You Know about Vitamin D?

Vitamin D [Vit-D3 (cholecalciferol)] – a unique fat-soluble vitamin (steroid hormone) is produced when your body is exposed to the sun light or ultraviolet light. It is transported to liver and kidneys where it is further converted to active 1, 25-dihydroxyvitamin D (calcitriol). As a hormone, it controls phosphorus, calcium, and bone metabolism and neuro-muscular function.

A diet deficient in vitamin D in conjunction with inadequate sun exposure causes osteomalacia in adults and rickets in children. However, vitamin D deficiency has become a worldwide issue in the elderly and remains common in children and adults.
